Abstract
The invention addresses the coupling of light between one or more multicore fibers and optoelectronic transducers, such as lasers or photodetectors, and/or single core fibers. More specifically, the invention utilizes a single microlens element to couple multiple optical data signals between multiple optoelectronic transducers and multiple cores of a multiple-core fiber (MCF), or to couple signals from multiple single-core fibers to multiple cores of a MCF. At least one optoelectronic transducer and at least one fiber core are substantially removed from the microlens axis and the MCF axis, possibly by different amounts, and cores of the MCF may optionally be polished to be non-telecentric to the axis of the microlens element.
